FIRE KINDLER. 1

n I'Application filed .Tune 8, .1927. sen in 197,247. w

This invention'relates to stoves,furnaces and like heaters and moreparticularly to types using coal as a fuel.

In the past, when it was desired to'build a fire in such stoves it wasnecessary to first burn paper, then wood and finally coal in order tobring the temperature of the fire up to the ignition point of thecoal. 7

Obviously, such a method is slow and lo tedious, requiring great care tosee that the fire does not go out or become smothered through lack ofoxygen.

Itis therefore the main object of this in-v vention to provide simpleand quick' means for raising the temperature of the coal to its ignitionpoint, thus eliminating the need of burning fuel having lower ignitionpoints than the coal. 7 I

A further aim is in the provision of a guard adapted to protect the coalheating means against clogging, thus assuring positive operation at alltimes.

A still further characteristic is to rovide coal heating means which,when the uel has reached its combustion ofi".

These and other objects, which will become apparent as the descriptionprogresses, are attained by the novel construction, com

bination and arrangement of elements, herepoint, may be shut inafterdelineated and depicted in the accompanying illustration, constitutingan important component of this disclosure, andv in which Figure 1 is afront elevational ,view of a furnace equipped with an embodiment of thisinvention, part of the casing being broken away to show the innerconstruction.

Figure 3 is a fragmentary side elevational view of the coal heatingmeans, drawn to an enlarged scale.

Figure 4 is a top plan view of the same 5 taken in a plane at rightangles to Figure 3,

Figure 5 is a partial transverse sectional view taken on line 5--5 ofFigure 3 drawn to a further enlarged scale.

Figure 6 is a partial transverse sectional, partial top plan viewtakenon line 6-6 of Figure 7. n i

Figure 7 is a front elevational view showing the'application of thisinvention to a type of boiler, the embodiment having been indicated inbroken lines.

,In the drawing, the numeral 10 generally designates a furnace of thecoal burning type having various compartments, shelves, etc., all of theusual construction.

One of the side walls of thefurnaceis lined with a fairly thick sheet 11offire brick or other heat resisting material and rising from the floorof'the furnace, spaced from the wall 11, approximately half I the heightthereof, is a thinner metal partition 12.

Intermediate the partition 12 and wall 11,

near the top of the former, is agrate 13 .supported'by brackets 14 fixedto the wall and partition and securedto the same, near the bottomsthereof, is a second pair of oppositely disposed brackets 15 supportinga metal plate 1'6-on which there is a pan 17 to catch whatever materialmay fall between the interstices of the grate 13.

Passing through the sheet 11 and the adjacent side wall of thefurnace,'just below the grate 13, is a pipe 18 connected to a supply ofgas, the ipe being bent at a right angle to form a tegral T-portion 20,disposed in the same horizontal plane, the burners being provided withdouble rows 21 of apertures from which gasmay flowto be burned and theT-portion being supported on brackets 22.

Secured by bolts 23 on the ends of the burner 19, are clamps 24 to whichis fixed an elongated, transversely arcuate guard'25, spacedly coveringthe openings 21 against cinders, etc. from the grate 13.

In Figures 6 and 7 the numeral 30 designates anouter, cylindrical casingin which is placed an inner, eccentric casing 31, provided with a grate32 below which is disposed a burner 33 of the type above described,supplied with gas through a pipe 34.

Thus, when it is desired to build a fire, a quantity of coal is placedon the grate and the gas burner is lit so that the flames therefromreach the coal and heat the same until the fuel will continue to urner19 having an in- I claim as new and desire to secure by LettersPatent,is
